OnCoはがんのためのオープンリポジトリです。すべてのコーパス、すべてのページ、ソース、図面、翻訳、スクリプトがオープンライセンス(データはCC BY-NC 4.0、コードはMITで)でこのリポジトリに保存されており、公開され、問題やプルリクエストを修正し、患者、臨床医、研究者、企業、AIエージェントが無料で閲覧・再利用できます。サイトに知られていないことを知っている場合は、問題やプルリクエストを開いてください。ゲートはすべての貢献に対して同じチェックを行います。

OnCoは腫瘍学の公開引用済みナレッジグラフであり、がんに関する完全な情報優位を目指しています:がん、フロント、技術、標的、バイオマーカーの読み取り、治療と検査、企業、機関、個人、経路、試験、主要論文、ジャーナル、ペアリング、ロードマップ、ボトルネック、アイデア、各1ページずつ、技術層の前に簡易なTL;DRとあらゆる方向へのリンク付きです。読者はグローバルビューから自分の国を選択し、「承認」とは規制当局の判断を意味します。

OnCo: Total information dominance on cancer.

Live: https://onco.cc

OnCo is an open repository for cancer. The whole corpus, every page, source, drawing, translation and script, is in this repository under an open licence (CC BY-NC 4.0 for the data, MIT for the code), built in public, corrected through issues and pull requests, and free for patients, clinicians, researchers, companies and AI agents to read and reuse. If you know something the site does not, open an issue or a pull request: the gate runs the same checks on every contribution.

OnCo is a public, cited knowledge graph of oncology, aiming at total information dominance on cancer: every cancer, front, technology, target, biomarker readout, treatment and test, company, institution, person, pathway, trial, key paper, journal, pairing, roadmap, bottleneck and idea, one page each, with a plain-English TL;DR before the technical layer and links in every direction. Readers start in a Global view and pick their country, so “approved” means their regulator’s verdict. It exists so that a patient, a carer, a clinician, a scientist, an investor or a policymaker can walk from any object to everything connected to it and see the state of the art, the history, what is being done about each problem, and what is coming.

The website is one surface. The same corpus ships as:

• the site (https://onco.cc): tables with filters, tooltips on every technical term, molecule and target renderings, animated schematics, a graph explorer, Ask OnCo question answering, a living-with-cancer area (side effects, symptoms, second opinions, hair loss, complementary approaches graded by evidence), coverage of what insurers and the NHS pay for, and a completeness dashboard that states how much of the known world each kind covers;
• a static JSON API under https://onco.cc/api/v1/ with CORS, per-entity Markdown context files for language models, Atom feeds and RDF triples;
• an MCP server and a command-line tool (packages/), so agents and scripts can search, fetch, compare and ask over the corpus;
• browser WebMCP tools for read-only record search and lookup in supporting browsers (implementation and testing);
• eight interface languages with translated TL;DRs where a translation exists.

Work in progress. Verify at source. Every fact is being built and checked in the open and may be incomplete, out of date or wrong. Nothing here is medical advice. Do your own research and check anything that matters at its primary source, which every page links.

Current counts live at https://onco.cc/about/ and print from npm run validate. This file deliberately carries no numbers, so it never goes stale.
